Check the settings for your application pool - allow 32-bitness. You may also need to do something for your dot net settings in that regard:

To set up ASP.NET for 32 bit:

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis -i

To set up ASP.NET for 64 bit:

C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727>aspnet_regiis -i

Don't know what this does, and why is this necessary, but I had problems until I found these lines on Rick's site.
